CLOSURE FUR RECEPTACLES.

Application filed July 9, 1913.

To all whom it may concern:

Be it known that 1, RICHARD M. H01.- LINGSHEAD, a citizen of the UnitedStates, residing at Riverton, in the county of Burlington, State of NewJersey, have invented a new and useful Closure for Receptacles, of whichthe following is a specification.

This invention relates to closures for receptacles or containers, andhas for an object to provide a closure particularly adapted for use inconnection with receptacles for enamel, glue or like viscous liquids,the nature of which ordinarily causes theclosures to stick to thecontainer or receptacle and render the removal thereof exceedinglydifficult. My invention therefore is devised to overcome said troubles,as will be hereinafter described.

For the purpose of illustrating my invention, 1 have shown in theaccompanying drawings one form thereof which is at present preferred byme, since the same has been found in. practice to give satisfactory andreliable results, although it is to be understood that the variousinstrumentalities of which my invention consists can be variouslyarranged and organized and that my invention is not limited to theprecise arrangement and organization of these instrumentalities asherein shown and described.

Figure 1 represents a perspective of a closure embodying my invention,the same being shown attached to the top of a receptacle and also havingan implement in position thereon to aid in the removal of the closure.Fig. "2 represents a section of a portion of the closure showing a diskmember ready to be inserted therein. Fig. 3 represents a section of thesame showing the disk member in assembled condition. Fig. 4 representsasection of the complete closure mounted upon a receptacle.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings :-1 designates a screw-threaded neck member ofannular form having an internal circumferential flange 2 encircling theopening 3, which is formed by the projecting annular lip 4. The flange 2forms between the said lip 1 and the neck wall 1, a seat in which islocated, in the present instance, a washer 5 of suitable material whichforms a means to prevent leakage through the joint formed Specificationof Letters Patent.

between the neck member 1 and the closure body 6, this latter memberbeing suitably screw -threaded for engagement with the neck member 1, aswill readily be understood.

7 designates a bell formed by outwardly flaring the walls of the annularbody member 8, which bell terminates in a circumferential flange 8,which as here shown, has'its outer edge 9 curled or crimped inwardly toact as a retainer for a disk 10 which has previously been insertedwithin the flange 8. As shown in Fig. 2, said disk 10 has acircumferential upturned rim which rests against the inner side of thecircumferential flange 8, thus reinforcing the latter from within, whilesaid disk stifi'ens the upper portion of the body member also fromwithin and prevents collapsion thereof. The body member 6 is closed atthe opposite end by the bottom or base 11 which is formed integral withthe said body and provided with a depressed bead 12 which is adapted toseat upon the washer 5 and form a tight joint at the desired points.

' l3 designates a air of slots cut at suitable poin'ts in the ange 8 andpreferably in alined relation with respect to each other for the purposeof receiving a nail, file,

knife-blade or like implement 14, which may be used to assist in theremoval of the body member 6 from the neck member 1.

In using the closure, the neck member 1 is soldered or otherwisesecurely afiixed to a suitable receptacle as 15 with the opening 3alined with the opening 16 of the receptacle and it will be apparentthat when the parts are in assembled condition as shown in Fig. 4, theopening 3 is eflectually closed and leakage guarded against by theprovision of the washer 5.

The novel method of forming the above described product consists infirst forming the screw threaded annular neck member by stamping out acap member, forming the internal and external thread thereon and thenpunching the opening 3. The washer 5 is next located as shown in Fig.4:. The closure body 6 is next pressed into the form of a cap withclosed base 11, the depressed bead 12 around the same, the bell '1' andflange 8 shaped thereon, which operation is followed by the internal andexternal threading step. The disk 10 is now pressed into place and theflange 8 crimped, as shown at 9, in ordcr to hold the disk in positionand form.

the hollow body closure complete. The slots 13 are now out in the flange8 and the closure is ready for insertion withinthe neck member 1. n

It will now be apparent that I have devised a novel'closure member andprocess of forming the same whereby a container or receptacle forviscous liquids such as enamel or the like may be equipped with theaforesaid closure and be secured against leakage of the contents. Itwillbe noted that the body member 6 seats accurately upon the flange 4of the opening 3 and seals the discharge opening 16 in an eflectivemanner. It will further be apparent that the washer 5 is ressed betweenthe bottom of the bead 12 o the closure body 6 and the circumferentialflange 2 so that even should leakage occur between the bottom 11 andflange 1 it will be confined by the washer 5 and prevented from passingalong the joint between the neck 1 and body 6.

By the foregoing construction it will be seen that the opportunity forthe enamel or like liquid to leak around the, .body 6 and set, therebycausing the closure to adhere or stick to the neck 1 is reduced to aminimum. In case there is a tendency of the body 6 to stick to thewasher 5 I have provided in the slots 13 a means whereby an implementmay be utilized to readily break the sealing .action and permit theclosure to be removed.

weakened by the slots 13, but new strength is gained by the use of, saidplurality of.

thickness of the portion in question.

Having thus described my invention, what I claim as-new and desire tosecure bv Letters Patent, is

A receptacle having an opening in the top Wall thereof, a screw threadedneck having on'its base an inturned flange which also is seated uponsaid top and secured thereto, a lip rising from the inner end of said.flange around said opening, said neck, flange and lip forming adepressed seat on said top around said opening therein, a washeroccupying said seat, anda threaded closure body adapted to be fitted tosaid neck and having a closed base adapted to engage the top of saidlip. and having a depending bead in its circumferential portion adaptedto descend into said seat.
